Title: Photolithography system and method of fabricating thin film transistor array substrate using same
Inventor: PARK WOON-YONG
IPC: G02F1/1362
Filed: 2000-07-10
Granted: 2001-10-11
Abstract: A method of fabricating a thin film transistor array substrate for a liquid crystal display includes the step of forming a gate line assembly with gate lines, gate electrodes and gate pads. A gate insulating layer, a semiconductor layer, an ohmic contact layer and a conductive layer are sequentially deposited onto the substrate with the gate line assembly. A photoresist film is deposited onto the conductive layer. The photoresist film is first exposed to light at a first light exposing unit to form a data line assembly, and secondly exposed to light at a second light exposing unit to form a channel such that the photoresist film has a first portion placed over the data line assembly area with a predetermined thickness, a second portion placed over the channel area with a thickness smaller than the thickness of the first portion, and a remaining portion with no thickness. The photoresist pattern, the conductive layer, the ohmic contact layer and the semiconductor layer are etched to form a data line assembly, a semiconductor pattern, and an ohmic contact pattern. The data line assembly includes data lines, source and drain electrodes, and data pads. The remaining photoresist film is removed, and a protective layer is formed on the substrate. The protective layer is etched together with the gate insulating layer to form first to third contact holes exposing the drain electrode, the gate pad and the data pad, respectively. Pixel electrodes, subsidiary gate and data pads are then formed. The two light exposing units can produce a photoresist pattern differing in thickness while making it possible to etch multiple layers once for all, thereby improving productivity and simplifying the processing steps.
